ABSTRACT:
A filter element comprises a dimensionally stable porous formed body with an interior that provides a space for unfiltered fluid or a filtrate space. The interior of the formed body is partially filled with a material of expanded ceramics that is coated with a catalyst material such that a flow channel remains open. The material that is coated with catalyst material is provided in the form of a dimensionally stable catalyst body which is inserted into the interior such that it adjoins the formed body.
